MAP OF INDUSTRIAL MINERAL OCCURRENCES IN THE NATIONAL FORESTS OF ARIZONA
This map shows the locations of quarries, mines, prospects, occurrences, rock exposures, and (or) outcrop areas for twenty-two industrial mineral commodities (exclusive of sand and gravel) within the boundaries of the National Forests in Arizona. The map was prepared as part of a mineral resource appraisal of the Mexican spotted owl habitat in National Forest lands. The accompanying pamphlet includes brief descriptions of the commodities and a listing (table 1) of location and production data for each occurrence of a particular commodity. The data used to compile the map and pamphlet are chiefly from Phillips' (1987) tabulation of industrial mineral occurrences in Arizona and from Bates (1969). Geologic contacts are from Wilson and others (1969) and Reynolds (1988). The information shown on the map is similar to the nonmetallic mineral occurrences map of McCrory and O'Haire (1965) except that it was compiled from the updated data of Phillips (1987). No claim is made for completeness of this compilation and the user should bear in mind that some published and unpublished sources likely have been missed and that the data are no more accurate than the data sources.
The commodity location data in Phillips (1987) are given in terms of township, range, and the nearest section; thus locations shown on the map are accurate only to within 1 mi. A more accurately located industrial minerals data base, using coordinates of latitude and longitude, is in preparation by the U.S. Geological Survey (USGS) in cooperation with the Arizona Geological Survey (Greta Orris, USGS, oral commun., 1992). This data base will be available in the Mineral Resource Data System (MRDS), possibly by the end of 1993.
COMMODITY DESCRIPTIONS AND NOTES Asbestos (Chrysotile)
Chrysotile asbestos, a hydrous magnesium silicate mineral (Mg3[Si205](OH)4), commonly occurs as veins of silky fibers. In Arizona, chrysotile was formed as a result of alteration of the Mescal Limestone in the Proterozoic Apache Group by intrusion of diabase sills about 1,100 Ma (Shride, 1967). The area designated on the map by wide-spaced horizontal ruling corresponds chiefly to the outcrop area of the Apache Group and diabase sills. Although zones of asbestos alteration are locally common at the contact between the Mescal Limestone and diabase sills, they are of limited extent and are not necessarily present throughout this area. The close-spaced horizontal ruling indicates areas of numerous chrysotile occurrences. Individual asbestos mines, prospects, and occurrences listed in table 1 were not plotted on the map because there are too many of them. Table 1 lists 57 asbestos locations, some of which include several mines or occurrences.
Because of its fibrous habit, with some fibers as long as 15 cm, chrysotile can be woven into heat-resistant textiles in addition to use in packings and gaskets. It is also used in asbestos cement, floor tiles, brake shoes, and as a strengthener in plastics and paper.
Chrysotile asbestos has not been mined in Arizona since 1982 because of U.S. Environmental Protection Agency (EPA) restrictions on the use of all types of asbestos. Chrysotile asbestos, however, is considered by many scientists to be
considerably less carcinogenic than the crocidolite variety of asbestos (Stone, 1991). Thus, the possibility exists that chrysotile asbestos may receive future EPA approval for use in some applications, and production of this mineral in Arizona may resume.
BariteBarite (BaSO4), a very heavy mineral with a specific gravity of 4.5, is used
chiefly for weighting oil well drilling fluids. Other uses include the production of barium chemicals and paint. In Arizona the main occurrences of barite are in veins associated with faults, breccias, and fracture zones. A total of 26 locations, some including several mines and occurrences, are listed in table 1 and are plotted on the map.
Basalt, cinders, and scoriaBasalt is a volcanic rock that contains less than 52 percent silica. It occurs as
dense, black lava flows and as highly vesicular flows and pyroclastic deposits (scoria and cinders). The areas marked by diagonal ruling and small hand-drawn asterisks (indicating cinder cones) on the map are underlain by young Quaternary and Tertiary (less than 4 Ma) volcanic rocks, predominantly basaltic in composition. Quarries are abundant in this area. The total area of basalt outcrop is actually more extensive, but includes older upper Tertiary (4 to 8 Ma) basalt and cinder cones (Wilson and others, 1969; Reynolds, 1988). Individual quarries in basalt and in cinders and scoria are shown in the area of older rock. The younger rock is considered superior because it is not as indurated or weathered as the older rock (Bryan, 1987). One location for basalt is listed in table 1 and 21 locations for cinders and scoria. All sites are plotted on the map.
Uses of basalt, cinders, and scoria include concrete aggregate, railroad ballast, riprap, and manufacture of rockwool insulation. Scoria and cinders are commonly substituted for sand and gravel in construction aggregate.
ClayClays are chiefly hydrous aluminum silicate minerals that have a particle size
of generally less than 2 micrometers, and are more or less plastic when moist. These minerals occur as beds of clay or shale interbedded with other sedimentary rocks in sedimentary basins, as matrix and cement in sandstone, as alteration products in the diagenesis or weathering of volcanic ash, and as products of hydro thermal alteration.
Phillips (1987) did not include common clays (generally illitic clay used in the manufacture of brick and tile) in his tabulation of industrial minerals. Thus, the 16 clay occurrences shown on the map and listed in table 1 are chiefly bentonite (montmorillonite), kaolin, or unidentified clay minerals. These clays occur in a variety of depositional environments and in association with several host rocks.
Bentonites are dominantly either high-swelling sodium type and low-swelling calcium type. Low-swelling bentonite is used in refining and decolorizing oil, and in desiccants. High-swelling bentonite is used in oil well drilling mud, pharmaceuticals, canal and reservoir linings, and heap leach pad sealants. Kaolin is used in paper- coating material, and in the manufacture of stoneware, refractory brick, and ceramic products.
DiatomiteDiatomite is a sedimentary rock composed of a large percentage of microscopic
aquatic plants called diatoms that have shells made of opaline silica. Diatomite deposits are common in lacustrine fades of basin-fill rocks in southern and western Arizona, but the deposits currently are considered to be too thin and too impure to be exploited using present technology in existing economic conditions. A total of four diatomite locations are listed in table 1 and plotted on the map.
It is the microscopic size of the diatom shells that give diatomite its desirable properties. Nearly half of the diatomite produced is used as a filter aid. Other uses are as fillers and in thermal insulation.
FeldsparThe feldspar group of minerals are anhydrous aluminum silicates of potassium,
sodium, and calcium. Taken as a whole, feldspars are the most abundant constituents of igneous rocks. The members of the group that find common use as industrial minerals are the potassium feldspars (orthoclase and microcline) and the sodium end member of the plagioclase feldspar series (albite). The chief uses of feldspar are in the ceramics and glass industry. The potassium and sodium content of ground feldspar acts as a flux when the powder is added to ceramic mixes, lowering the melting point. Feldspar powder is added to glass mixes for its alumina content. Additional alumina increases the resistance of glass to impact, bending, and thermal shock.
Although feldspar is common and widespread in nearly all igneous rocks and is present in many metamorphic and sedimentary rocks, pegmatites are the only source exploited for feldspar in Arizona. Productive and potentially productive pegmatites occur in older crystalline rocks in a belt that runs from Lake Mead in Mohave County southeastward to Cochise County. Five locations are listed in table 1 and plotted on the map for feldspar.
FluorsparFluorspar or fluorite (CaF2) is translucent to clear, and varies from colorless
or white through green, yellow, brown, blue, and purple. It occurs as veins, aggregates of cubic crystals, and as granular masses, and commonly crystallizes with calcite, quartz, and pyrite. Fluorspar occurs in Arizona chiefly as veins in fissures and breccia zones associated with faults. A total of 29 fluorspar locations are listed in table 1 and are plotted on the map.
Uses of flourspar are in the manufacture of hydrofluoric acid, as flux in steel making, and in the production of ceramic materials.
GypsumGypsum, CaSO4.2H2O, is soft (can be scratched with a fingernail); commonly
white, but can be colorless, gray, pink, or brown; and can be granular or finely to coarsely crystalline. Curved fibrous crystals are common. Gypsum is an evaporite mineral that precipitates from hypersaline lacustrine or marine water, either as interbeds with salt and claystone or disseminated in clayey sedimentary rocks. Gypsum deposits must occur in fairly pure thick beds to be economically important. The gypsum deposits in the National Forests in Arizona are found in Tertiary lacustrine rocks. Fourteen locations for gypsum are listed in table 1 and plotted on the map.
Gypsum is used either "as is" or it is calcined. Uncalcined gypsum is used as an additive to portland cement and as an agricultural soil conditioner. Gypsum that has been calcined at 250° to 400°F produces plaster of paris. Calcining at 900° to 1000°F produces anhydrous gypsum (anhydrite) that is used as a desiccant and in specialty cement.
Limestone, dolomite, and marbleLimestone and dolomite are lacustrine and marine sedimentary rocks. Pure
limestone is composed of calcium carbonate (CaCO3); dolomite is calcium-magnesium carbonate (CaMgCCO3)2). Marble is either limestone or dolomite that has been metamorphosed, which commonly has to effect of making the resulting rock whiter and more coarsely crystalline. Limestone and dolomite do not usually occur as pure end members, but tend to contain varying amounts of magnesium. In addition, because they are sedimentary rocks, they may contain interbedded shale, sandstone, or chert. Twenty-nine limestone, dolomite, and marble locations are listed in table 1 and plotted on the map.
The uses of limestone, dolomite, and marble depend on either their physical properties or their chemical composition. Uses that are not composition dependent are as smelter flux and as crushed rock for aggregate, ballast, poultry grit, whiteners and fillers. Limestone or limestone marble is required for the manufacture of Portland cement and is also used in the treatment of stack gases.
MicaMembers of the mica group of minerals are complex hydrous potassium
aluminum silicate minerals characterized by platy morphology and perfect basal cleavage. Of the mica minerals, muscovite, phlogopite, and lepidolite are the most important economically. The eight muscovite occurrences within the National Forests (table 1) are nearly all in pegmatites.
Mica is marketed as sheet mica and scrap mica. Sheet mica must be flat and in pieces larger than 1 in. across. Its chief use is as an insulator in the electrical and electronics industry. Scrap mica is ground and used mainly in the manufacture of joint cement and paint.
PerlitePerlite is a glassy volcanic rock with the composition of rhyolite (greater than
69 percent SiO2) and high water content (2 to 5 percent). When perlite is crushed and heated to between 1,400° and 2,000°F, the contained water is converted to steam and the perlite granules expand 4 to 20 times to pruduce light, cellular particles. Twelve perlite locations are listed in table 1 and plotted on the map.
Perlite is important in the construction industry for insulation, light weight aggregate, and acoustical tile. Other uses are as fillers, extenders, and carriers.
PumicePumice is a light-colored highly vesicular glassy volcanic rock that generally
contains more than 69 percent SiO2 . Because of its light weight and the fact that many vesicles are closed off from one another, some blocks of pumice will float on water. Twenty locations for pumice are listed in table 1 and shown on the map.
Principal uses of pumice are for concrete aggregate, landscaping, abrasives, roofing granules, and in creating stone-washed garments.
SaltSalt, or sodium chloride (NaCL), is an evaporite mineral that precipitates from
hypersaline lakes in closed basins. It is commonly interbedded with gypsum and clay. Salt crystallizes in the form of cubes and is transparent and colorless when pure. Only one location for salt is listed in table 1 and plotted on the map.
Salt is used chiefly in the chemical industry for the production of chlorine and caustic soda. Other uses include the de-icing of roads, the food processing industry, livestock feed, and petroleum refining.
Silica, quartz, and quartziteQuartz or silica (silicon dioxide, SiO2) is a component of many igneous rocks,
and is abundant as veins in mineralized areas. It is commonly colorless or white, but a wide variety of colors is possible depending on the content of trace element impurities. Because of its resistance to corrosion, fracture, and abrasion, quartz persists through weathering and erosion and is one of the most abundant detrital minerals. Quartzite is a sedimentary or metamorphic rock that consists of detrital quartz grains held together with silica cement.
Most of the quartz and quartzite produced in Arizona is used as metallurgical flux in copper smelters. There may be occurrences of quartz with properties that would be useful for other purposes, but the quartz occurrences of the state have not been evaluated adequately. Twenty-six locations for silica, quartz, and quartzite in the National Forests are listed in table 1 and shown on the map.
SandstoneSandstone beds of the Coconino Sandstone and Moenkopi Formation are
quarried for dimension stone in northern Arizona. The middle Permian Coconino Sandstone consists of white, pink, and red, well-bedded, fairly well consolidated sandstone. It is used chiefly as flagstone and is shipped throughout the U.S. and to Japan. Thick-bedded, maroon and chocolate-colored sandstone near the base of the Triassic Moenkopi Formation was quarried extensively prior to the 1930's. The sandstone of the Moenkopi is calcite-cemented and is thus softer than the silica cemented Coconino Sandstone. Its principal use was as large blocks for building stone (Kieth, 1969).
The outcrop belts of the Coconino and Moenkopi are shown on the map, but individual quarries are not indicated on the map or listed in table 1. Quarry activity for the Coconino Sandstone is presently centered north of Ashfork.
Sillimanite groupThese are aluminous silicate minerals and include sillimanite, kyanite,
andalusite, dumortierite, and topaz. The chief utility of these minerals is that, upon firing at high temperature, they convert to mullite, a refractory mineral able to withstand thermal shock. Their uses, among others, include the manufacture of glass furnaces, molten metal handling equipment, and spark plug insulators.
In Arizona, the sillimanite group of minerals are known to occur in Precambrian metamorphic rocks, although the size and quality of the occurrences have not been explored adequately. Three locations for silimanite group minerals are shown on the map and listed in table 1.
Sodium sulfateThe main sodium sulfate minerals are thenardite (Na2SO4), mirabilite
(Na2SO4.10H2O), and glauberite (Na2SO4.CaSO4). These are evaporite minerals and are found in brines and interbedded with other evaporite minerals such as gypsum and salt. Only one location for sodium sulfate is listed in table 1 and plotted on the map.
Sodium sulfate is used for the digestion of wood pulp, the manufacture of sodium based chamicals, and in ceramics, dyes, ink, and animal feed supplements.
StrontiumIn Arizona, strontium occurs in the form of the mineral celestite (SrSO4).
Celestite is found in cavities in dolomite and dolomitic limestone, in evaporite deposits, and in hydrothennal veins. Celestite is important as a source of strontium, which is used in pyrotechnics. One celestite location is listed in table 1 and shown on the map.
VermiculiteVermiculite is a sheet silicate formed mainly from the low temperature
alteration of biotite. Vermiculite commonly occurs in small amounts in many igneous and metamorphic rocks. Larger deposits of Vermiculite are inferred to have formed by the alteration of mafic rocks by silica-poor or volatile-rich intrusives, followed by supergene alteration.
Heating in the range of 800° to 2,000°F drives off the water of hydration, which in turn forces the cleavage plates of the mineral apart in an accordion-like fashion. This results in a lightweight material that is incombustible and has good thermal insulating properties. Principal uses of vermiculite are as lightweight aggregate, thermal insulation, agricultural soil supplement, and as carriers, fillers, and extenders.
Only one location for vermiculite is listed in table 1 and plotted on the map.
WollastoniteWollastonite (CaSi03) is a brilliant white contact metamorphic mineral that
occurs in the aureole between impure limestones and granitic intrusive rocks. It is commonly associated with garnet, diopside, epidote, calcite, and quartz. Two Wollastonite locations are listed in table 1 and shown on the map
Wollastonite is used in making tile and as a filler, extender, and whiting agent in paints and plastics.
Zeolite groupThe zeolite group of minerals comprises more than twenty-five minerals
defined as hydrated aluminosilicates of the alkali and alkaline earth metals, with an infinitely extended three-dimensional anion network. The porous character of the zeolites allows them to act as molecular sieves for separating mixtures based on the size and shape of the molecules or for the selective adsorption of gases.
In Arizona, natural zeolite deposits have been formed by the diagenetic alteration of volcanic ash. The following zeolite minerals have been reported in these deposits: clinoptilolite, chabazite, mordenite, phillipsite, analcime, and erionite. A total of seven locations for zeolite group minerals is shown on the map and listed in table 1.
